libreoffice-7.5.4.2 unwind.h:33:3: error: redefinition of enumerator

Home workstation in preparation for 12- EOL.

After OS update 12.4 -> 13.2 STABLE and reinstalling tons of ports, the 
only remaining problem is libreoffice.

stable/13-cbca92986

gmake[2]: *** [Makefile:289: build] Error 2

I get lots of,

etc etc

So, is some leftovers from 12.4 causing this? Do I need to update a llvm 
version? Or is it another port that needs to recompile against new OS?

Hints appriciated...
